Points saillants

Have fun out there this weekend but watch out for isolated shallow snowpack areas, these areas exist in the terrain and travelers need to keep this in mind.  Large triggers such as a cornices still have the potential to trigger deep instabilities. PJ

    The lower half of the snowpack is weak due to the presence of basal depth hoar and facet layers. Natural and human triggering is unlikely, but possible in steep open slopes with shallow snow, or south and west facing terrain during mid-day.

Weather Forecast

A few centimeters of snow is forecast for sunday and then a new pulse of cold North air on Monday. 

Snowpack Summary

A few cm's of cold loose snow sits on the surface. The base of the snowpack is weak facets and depth hoar with a 40-60cm slab of stiff snow over top. Triggering would be difficult but is possible in open, shallow snowpack areas such as ridgetop features, cross-wind affected terrain features or moraines.

Avalanche Summary

No new avalanches reported today.
